SYSLOG, JESMSGLG.
An attempt to log on to application app was made from ipa via port port to subsystem ID ssid. The logon security exit defined in the subsystem rejected the logon.
ipa is the TCP/IP address of the requestor. The message shows the direct TCP/IP address of the client if the client's TCP/IP address is included in the logon request. Otherwise the message shows the TCP/IP address of a server/router.
It may be impossible to log on (depending on the application that has requested the logon).
Identify and eliminate the error.
